Diamonds are pave channel and prong set. Colour is intense and marvellous gleam. Beautiful quality and top class workmanship. Form of a flower spray, with a full bloom curving above a bud, with flowing foliage and stems. Condition very good. No damage / loss of any sort. Independent appraisal available to new owner upon request. Note: this brooch was independantly appraised. The appraiser is a well-qualified GIA but doesn't have the equipment to identify origin of diamonds, nor whether they were treated. To quote her "they do not look treated, but I can't write that". Therefore, this brooch was valued as per treated yellow diamonds, while in fact, there is a very good chance that they are genuine, natural, unheated, untreated stones.
